Late gadolinium enhancement CMR findings in athletes following mildly symptomatic COVID-19 infection. Yellow arrows indicate areas of LGE. A-B: small focal intramural LGE in the vicinity of the posterior RV insertion point. This pattern observed in equal proportions of COVID(+) and COVID(−) athletes, and considered as non-specific because suggestive of physiological remodeling. C: Intramural and sub-epicardial LGE lesion on infero-latero-basal LV segment, shown in short axis and 3-chamber views (top and bottom panel, respectively). The patient had experienced a mild symptomatic SARS-CoV-2 infection 65 days prior to the CMR study, with no clinical signs of myocarditis. Echocardiography, ECG and troponin tests were negative at inclusion. This CMR finding being suggestive of a post-inflammatory origin, scarring secondary to COVID-related myocarditis could not be ruled out
